1 and win8. 1 have been out for a long time. Personally, I like win8. 1. Compared with win8, it is much improved and more convenient to use, but it really took me a long time to install the graphics card driver. My notebook is Thinkpad E40, and the graphics card is ATI Mobility Radium HD 4500 series, that is, AMD graphics card, which is an old graphics card. After installing win8. 1 system, whether it is 32-bit or 64-bit, it is impossible to install the official win8 driver released by AMD with the driver wizard and driver life.
2. Online search didn't find a suitable solution either, and it was finally solved after a period of exploration. The main reason is that win8. 1 system will automatically update Microsoft's graphics card driver for notebooks, which will prevent users from installing AMD's official driver, resulting in that neither the driver wizard nor the driver can install the correct driver (at least my notebook can't be installed, and it is impossible to verify whether other computers can also install AMD drivers). The reason why AMD drivers can't be installed after Microsoft drivers are installed is not clear. The date of the Microsoft driver signing certificate may be newer than the official AMD driver signing date (2012/116). Please also ask the great god who knows the driver's signature to help analyze the real reason.
3. After installing win8. 1 on the computer with ATI Mobility Radium HD 4500 series graphics card, the default graphics card driver of the system is "Microsoft Basic Display Adapter". The display of this graphics card driver on 1366*768 notebook is abnormal, and the highest resolution is only 1024*768. However, when the system is installed and connected to the Internet, the system will automatically update and install Microsoft's AMD driver, and the driver number is "ATI Mobility Radium HD 4500 Series (Microsoft WDDM V 1. 1)". This driver looks normal after installation, but after I installed photoshop CS6, the first time I use it, the software will prompt that there is something wrong with the driver, and photoshop has temporarily stopped the graphics hardware enhancement. "I didn't encounter other problems. Some people reported that they could not use the desktop version of AutoCAD 20 13.
